Velasco castle was built at the end of 14th century and mid-15th century. Due to its complexity, dimensions and conservation, it is the most important castle of Mena and one of the most interesting in the province of Burgos. The first documents of the tower dates back to 1397 when it fell, after sharing the heritage of Pedro Gomez de Porras, on Maria Alonso de Porras, married to Diego Sanchez de Velasco.
References:Visby Cathedral (also known as St. Mary’s Church) is the only survived medieval church in Visby. It was originally built for German merchants and inaugurated in 1225. Around the year 1350 the church was enlarged and converted into a basilica. The two-storey magazine was also added then above the nave as a warehouse for merchants.
Following the Reformation, the church was transformed into a parish church for the town of Visby. All other churches were abandoned. Shortly after the Reformation, in 1572, Gotland was made into its own Diocese, and the church designated its cathedral.
There is not much left of the original interior. The font is made of local red marble in the 13th century. The pulpit was made in Lübeck in 1684. There are 400 graves under the church floor.
